1. Purpose
LE-03MW CT is an electronic, 2-way three-phase electricity meter, designed for measurement
in a semi-indirect system. A built-in real-time clock allows energy consumption to be measured
by different tariff zones. RS-485 with Modbus RTU protocol and optical port compliant with EN62056
(IEC1107) provide remote reading and configuration of the meter.
2. Device characteristics
3-phase, 2-way energy meter;
Semi-indirect current measurement (direct measurement up to 6 A);
Energy measurement in four tariff zones;
Built-in real-time clock with battery backup for switching tariff zones;
Registration of total and tariff-divided consumption of:
•total active and reactive energy;
•active and reactive energy divided into individual quadrants;
8 time schedules that divide the day into tariff zones;
Possibility of billing energy according to different weekday and weekend schedules;
Ability to divide the year into 8 time periods. In each period the energy (for working days) can
be billed according to a different schedule.
Indication of network parameters (voltage, currents, active power, reactive power, apparent
power, power factor, frequency);
Calculation of power demand for individual tariffs;
Additional resettable energy consumption meter;
RS-485 port, Modbus RTU protocol;
Optical communication port compliant with EN62056 (IEC1107);
2 SO pulse outputs with programmable number of pulses per kWh/kVarh;
Multifunctional LCD display.

4.1. Description of the display elements
Current tariff indicator.
Symbol – indicates which
parameter group the value displayed in the numeric
field is associated with. It may be a tariff (T1, T2, T3 T4)
or phase (L1, L2, L3)
indicator.
Unit of the value shown in the numeric field of the display.
Symbols have the following meaning:
kW – active power
kWh – active energy
kVarh – reactive energy
VA and kVA – apparent energy
V – voltage
A – current
The numeric field of the display indicates the value of the frequency.
Data exchange via the communication interface.
Low battery indicator for the internal clock battery.
4.2. Control elements
Control buttons for changing the displayed value.
A list of displayed parameters is shown in the following table.

9.2 Current transformer
The current transformer ratio of the meter can be set remotely via the Modbus RTU interface or
locally using the PROG button.
To set it manually:
1) switch off and on the power supply of the meter;
2) press and hold down the PROG button;
3) release the PROG button after about 15 seconds;
4) the display will show a blinking CT value (for example 0005-5); the table of available settings is
shown below;
5) set the desired value of the current transformer ratio by pressing the button to the left or right;
6) wait until the transformer value disappears from the display.
Setting the transformer ratio via the RS485 interface requires the code value corresponding to the
selected current transformer to be written to register number 8.
Please note: The code designation of the transformer is created by writing the value of the
transformer primary current as a BCD number.

10. Manufacturer warranty
1. The meter is covered by a 24-month warranty from the date of purchase.
2. The warranty valid only with proof of purchase.
3. A warranty claim should be submitted at the point of purchase or directly to the manufacturer:
(phone [phone]; e-mail: [email protected]l)
4. During the warranty period, in the event of a justified complaint, the manufacturer undertakes, in
accordance with consumer rights legislation, to repair the device, replace it with a new one or
refund the payment.
5. Warranty claims will be processed within 14 days of delivery to the service centre.
6. The warranty does not cover:
- mechanical and chemical damage;
- damage caused by improper use or use not in accordance with the user manual instructions;
- post-sale damage resulting from accidents or other events for which the manufacturer, or the point
of sale is not responsible, such as damage during transport. etc.
7. The warranty does not cover activities that according to the instructions should be carried out by
the user, such as installation of the meter, electrical installation, installation of other required
electrical protection, checking etc.
Warning!
Do not make any changes to the unit by yourself. Doing so can result in damage to or improper
operation of the device, which in turn can lead to damage to the controlled device and pose a threat
to people operating it. In such cases, the manufacturer is not responsible for the resulting events and
may refuse the provided warranty in the event of a complaint.
